Until recently, Brachypodium rupestre was recorded as occurring in Hesse in
only a single location. Recent field work and a chance finding have revealed a further
five locations where this species occurs. These sites are located on anthropogenic
embankments of roads and floodwater retention basins, apart from at one site where the
plants grow under semi-natural conditions in an extensively cultivated riparian meadow.
All populations probably became established as a result of sowing, either directly or as a
result of diaspore drift from primary populations during flooding. In Hesse, B. rupestre
has the status of an established neophyte.
